To all whom '52 may concern Be it'known that I, Rrormnn T. NEWTON,

' a citizen of the United States of America,

residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Bummer Attachment Means, of which the following is a specification.

My invention relates to bumper attachment means, and particularly to a device for attaching bumper supporting arms to a chassis frame element'of channel or-anglesection. The object of my invention is to provide means of simple, strong construc tion well adapted to firmly secure the bumper to its chassis support in proper position, and readily applicable to bumpers and chassis of different types of construction. In certain features the present invention has resemblance to that of'my prior Patent No. 1,315,789, dated September 9, 1919.

In the accompanying dra-wings' Fig. 1 is a side elevation of an automobile chassis end and bumper showing the latter secured in position by'attaching means of one form in which my invention is embodied;

Fig.2 is a section on the line 22, Fig. 1; Fig. 3 is a partial broken side elevation showing one of the attaching elements;

Fig. i is a section on the line 4-4:, Fig. 1; Fig. 5 is a sideelevation of a modified construction;

Fig. 6 is a section on the line 6-6, Fig. 5; 1 Fig.7 is'a section on the line 77, Fig. 6;

Fig. 8 .is a. perspective of a! bumper se- I cured to the chassis endby another modified construction;

Fig. 9 is a vertical section through one ofthe attaching elements and associated parts;

. to the chassis. 5

Figs. 10 and 11 are perspectivesof de tails of the attaching device;

Fig. 12 is a vertical section of a further modified-form of construction;

Fig. 13.is a section on the line 1313,' Fig. 12; and I Fig. 14 is a plan of a detail.

In the construction illustrated in my patcntabove-mentioned, I have shown a bumper bracket with which are associated bolts for securing it and the bumper supporting arms In the present construction I have dispensed with the bracket and ened "the securing bolts directly with the bumper supporting arms, while in certain other modified constructions a bracket is employed, but in a much simplified construcion.

:iii t is to be understood that the present attaching means are well adapted to secure other types of bumpers than that illustrated, and to hold them to a bracket or other, elements have illustrated. tion with a: bumper 10 of well-known type comprising a'main impact member 11 and a supporting member 12 (Fig. 8) united thereto by a central clip 13, porting arms 14 and 15 of the impact andreenforcing members are carried back and secured to the chassis side bar 16.

In the form shown in Figs. l to 4; in-

attached to a chassis, I the invention in connecwhile the supelusive, the supporting arms 14 and 15 are pierced in register at 17 to receive the shank of a hookbolt 18, the end 19 of which overlies the lower flange 20 of the chassis side bar. The holding nut 21 screwing upon the shank of the bolt 18 bears directly or the latter and thus to clear'the heads of the rivcts23, which'serve to secure the tail of the usual spring-bolt casting 24; to the chassis side bar. are also slotted in register at 25 adjacent the ends of the supporting arms to receive a second bolt 26. The latter is of the type shown in my patent above mentioned, having at one end an elongated hook 27 adapted 95 to engage in the corner formed by the Tinction of the bottom flange 20 of the chassis side bar and the web 16 of the latter, or the side of the casting 24 which lies against said web, as indicated in the drawings. At 100 its other end 28 the bolt isofl'set at an angle 1 and its terminus threaded to receive the nut 29. Inter-posed between the nut 29 and the outer face of the bumper supporting arm the bumper supporting arm is substantially 11G vertical in adjusted position and bears against the bumper arm, The bearing piece side bar The two arms 14 and 15 '14: is a bearing-piece 30 pierced or channeled 106 ils ' is also provided with an offset lug .134 "which extends' fbeyond. the-ends of the- .bu'mpersupporting.Zarins and underlies the I I I I theportionz=50 of the stud,shank,"'.which;, 'n-

Engaging these holes are stud bolts' 46, the

The foot piece 71 of the stud bolt is serrated at 72 in one margin to engage corresponding serrations 73 in the face of the channel 74 in 'the upright against which it bears, thus locking This construction lacks the advantage found in the construction just reviously described, in that the pressure 0 the angle bolt upon the bracket does not tend to hold the ends of the bumper arms upon the bracket as well as to secure the bumper to the chassis side bar. The support of the bumper arms upon the bracket is obtained solely by the nut 75.

Various other modifications will readily occur to those dealing with the problem which do not depart from what I claim as my invention.
